CHARLES HAMMELMANN, OF BUFFALO, NEV YORK.

woon-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,860, dated May 13, 1890.

Application lecl September l, 1885. Serial No. 175,944. (No model.)

To aZZ whom t may concern.-

Be it known that I, CHARLEs HAMMELMANN,

of the city of Bulfalmin the county of Erie and State of NewYork, have invented new and useful Improvements in lVood-Planing Machines, of which the following is a specilication.

This invention relates to an improvement in that class of wood-planing machines which are provided with upright cutter-heads for matching or planing the edges of the boards.

The object of my invention is to improve the construction and operation of the machine in various respects; and my invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims. -f

In the accompanying drawings, consisting` of three sheets, Figure lis a side elevation of a planing-machine provided with my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-section in line 0c, Fig. 2, on an enlarged scale. Fig. 4 is a vertical section in line 'y y, Fig. 3. Fig. 5 is a top plan view of the sliding chip-breaker on an enlarged scale. Fig. 6 is a vertical section in line e e, Fig. 5. Fig. 7 is a cross-section of the upper portions of the matcher-frames. Fig. 8 is a cross-section in line a: -.r, Fig. l. Fig. 9 is a horizontal section in line c as, Fig. 8.

Like letters of reference refer to like parts in the several iigures.

A A represent the side frames of the machine; A, the bed upon which the boards to be planed are placed; A2, the standards supporting the front end of said bed, and a the horizontal driving-shaft, journaled in bearings attached to the lower portions of said standards.

a is the endless belt whereby the horizontal cutter-head is driven directly from the driving-shaft a.

b is the counter-shaft, journaled in bearings attached to the lower portions of the side frames A and driven from the driving-shaft a by a crossed belt b.

c is an endless belt running around a pulley c on the shaft b and around a pulley C,

the shaft of which is geared with the feedrollers in any suitable manner.

D is a tightener-pulley bearing against one side of the belt c and attached to an arm d, which is secured to one end of a horizontal shaft d', journaled in bearings on the lower portion of the side frames A.

d2 is an lupright arm secured to the opposite end of the shaft d', and d3 is a horizontal hand-rod attached to the upper end of the arm cl2 and extending` to the front en d ofthe machine, where the rod is provided with a handle d4. The frontportion of the rod d3 is provided on its under side with notches d5,

either of which can be engaged with a laterally-projecting pin (Z6, attached to the upper end of one of the standards A2, whereby the pulleyD can be tightened more or less against the belt c, as may be desired.

c represents the upright spindles, and E the matcher -heads secured lto the upper ends thereof. The matcherspindles are driven from the driving-shaft a in the usual manner. p

F F represent the upright frames in which the matcher-spindles are j ournaled, and which rest with their lower ends against a cross-bar f, secured to the side frames A A, and slide near their upper end upon a cross-bar f', secured to the bed A.

g g represent two horizontal screws whereby the matcher-frames F F are adjusted laterally in the machine. These adjustingscrews vturn in sockets formed in hangers G G', secured to the bed A, in which sockets they are held against longitudinal movement. The screw g works in a threaded opening g2 in the watcher-frame VF and passes loosely through an opening g3 in the matcher-fralne F and the screw g works in a threaded opening g4 in the matcher-frame F and passes loosely through an opening g5 in the matcherframe F. By means of the screws g g each matcher-head can be adjusted independently of the other, therebyincreasing or decreasing the distance between the two heads to correspond with the width of the boards, and both matcher-heads can be adj usted together laterally to one side et the machine, so as to bring the board under different portions of the horizontal cutter-head, thereby enabling the operator to use all parts of the horizontal eutter-head successively and equalize the wear of the knives of the same.

H represents a sliding chip breaker attached to the upper endet the mateher-frame F. This chip-breaker slides horizontally upon a plate 7l, which is secured to the upper end of the matcher-frame F, as clearly represented in Fig. 3. The point of the chipbreaker is bounded by astraightfaee ',which rests against the board, and a concave face 2, which is approximately concentric with the matcher-head and is turned toward the same.

la is a slot formed in the plate 7L at an angle to the face i' of the chip-breaker and approximately tangential to the concave face i2.

L is a block which slides in the slot 7c and io which the chip-breaker is secured by a screw-bolt Z and studs Z'. The latter are secured to the chip-breaker and enter sockets in the plate L, thereby preventing the chip breaker from turning on the bolt Z. The block L is provided witha depending lug in, through which passes a horizontal rod m', which is secured to the plate h, and which carries a coiled spring 'm2, whereby the chipbreaker is pressed against the board. The spring mi permits the chip-breaker to yield and holds it constantly in contact with the edge of the board. Upon removing the boltZ the chip-breaker can be detached from the block L, leaving the plate 7L unobstructed on its upper surface and in line with or below the bed A', thereby adapting the machine for wide surface planing upon removing the matcherheads.

N represents the longitudinal gnide-bar, which is secured to the bed A', and against which one edge of the board is placed. rlhe bar N is secured to the bed by screws 71whieh are adjustable in transverse slots n. 'lhc rear end of the guide-bar N is constructed with a chip-breaker N', which is secured to the upper end of the inatcher-frame F' by a screw n2, so that upon loosening the screws n the rear end of the guide-bar Nis adjusted with the matcher-frame F.

P represents a spring presser-bar, which bears with its rear end against the opposite edge of the board and holds the latter against the guide-bar N. The rear portion p of the presser-bar P is rigid and pivoted to the bed A' by a boltp', which is laterally adj ustable on the bed in a slot p2. The front portion of the presserbar is composed of a spring or elastic bar q, which is held near its front end in a slotted support Q. The spring q permits the rigid rear portion of the presserbar to yield to the inequalities in the width of the boards, and at the same time holds the rear end of the presser-bar constantly against the edge of the board and the latter against the guide-bar N. By adjusting the holt p' on the bed the position of the presser-baris adjusted to the width of the board.

The side frames. A are provided on 'their inner sides with vertical recesses or depressed ways r, and the bed A' is provided with depending legs R, which are arranged inthe re eesscs r and are capable of vertical movement in the same. y

s represents the vertical screws whereby the bed A' vertically adjusted between the side frames A. These screws turn in sockets s', formed on the inner sides of the lower por tions of the side frames, and workin threaded openings in the lower portions of the legs R. The latter are hollow and inelose the upper portions of the adj Listing-screws s, whereby the latter are protected against chips, dust, dsc. The screws s are rotated by means of a horizontal shaft si, geared with the screws in the usual manner. The bed is clamped in position after being adjusted by a screw-rod l, passing through vertical slots t' in the side frames A, as usual. The recesses r receive the legs R and adjusting-screws s, whereby the space between the side frames remains practically unobstructed, thereby enabling the drivingdielts to be run closely to the side frames.

I do not desire to claim in this application the construction of the belt-ti ghtenin g device shown and described herein, but reserve the right to claim said feature in a sepa 'ate ap plication to be filed therefor.

I claim as my inventionl. The combination, with the planer-bed, matcher-frame, and mateher-head, of a slotted plate'z, secured to the matcher-frame, a block L, capable of sliding in the slot of said plate, aspring m2, applied to the block L, anda chipbreaker Il, detachably secured to the block L, substantially as set forth.
